+    ======================
+
+    To make a contribution to a TianoCore project, follow these steps.
+    1. Create a change description in the format specified below to
+       use in the source control commit log.
+    2. Your commit message must include your "Signed-off-by" signature,
+       and "Contributed-under" message.

+       this document.
+    4. Submit your code to the TianoCore project using the process

+       not documented, then submit the code on development email list
+       for the project.
+    5. It is preferred that contributions are submitted using the same
+       copyright license as the base project. When that is not possible,
+       then contributions using the following licenses can be accepted:
